Singaporean and South Korean travelers can now rejoice as T’way Air, South Korea’s leading low-cost carrier, rolls out its most ambitious summer expansion yet. In response to surging demand, the airline will double its Singapore–Seoul flight frequency and launch a brand-new direct route between Singapore and Jeju Island starting August 16, 2025.
This bold initiative further strengthens air connectivity between Southeast Asia and South Korea during the peak travel season, offering cost-conscious travelers expanded choices and increased scheduling flexibility. As South Korea cements its place among Asia’s top travel destinations, T’way Air’s new services arrive at a time when cultural exchanges, tourism traffic, and regional mobility are thriving.
Daily Flights to Seoul—and More
Currently, T’way Air operates daily flights between Singapore Changi Airport (SIN) and Incheon International Airport (ICN), a vital hub serving the Seoul metropolitan area. These flights are operated with wide-body Airbus A330 aircraft, offering comfortable and budget-friendly transits.
Between July 23 and August 15, 2025, the carrier will increase this to twice-daily flights—a move that reflects robust passenger demand. During the period from August 16 to 31, there will be two flights every Thursday and Sunday, while one daily flight will remain on the other days. The schedule will return to one daily flight starting September 1.
The increase in service aims to accommodate travelers attending summer festivals, business events, and family reunions during Korea’s high season.
Jeju Island Joins the Network
In a landmark development, T’way Air is launching direct Singapore–Jeju flights on August 16, 2025, using its newest Boeing 737 MAX 8 aircraft. Jeju, often referred to as “the Hawaii of South Korea,” is known for its pristine beaches, volcanic craters, waterfalls, and UNESCO World Heritage Sites.
Until now, most Singaporean travelers had to route through Seoul or Busan to reach Jeju. This new nonstop route dramatically reduces travel time, enabling easier access to Jeju’s iconic landmarks like Seongsan Ilchulbong Peak, Hallasan National Park, and its coastal hiking trails.
The move is expected to attract honeymooners, wellness travelers, eco-tourists, and digital nomads seeking picturesque escapes beyond urban South Korea.

Korea’s Growing Appeal for Singaporean Travelers
Tourism between Singapore and South Korea continues to expand. According to the Korea Tourism Organization, over 720,000 Singaporeans visited South Korea in 2024—a 23% increase year-on-year. Jeju’s unique appeal as a nature-based destination and Seoul’s status as a K-culture epicenter make Korea a compelling choice for Singaporean travelers.
The South Korean government has also simplified e-visa processing and digital travel authorizations for ASEAN travelers, including Singaporeans, helping streamline entry procedures for tourists and business visitors alike.
Strategic Expansion for T’way Air
T’way Air currently serves over 60 destinations across Asia, including Japan, China, the Philippines, and Vietnam. The airline’s expansion into Southeast Asia is part of a larger strategy to tap into regional hubs like Singapore and Kuala Lumpur.
T’way’s addition of Singapore–Jeju flights aligns with Visit Korea Year 2023–2024 initiatives aimed at promoting regional destinations outside of Seoul. The Korea Tourism Organization has identified Jeju as a “core eco-tourism site” and is supporting campaigns to draw international footfall.
This expansion positions T’way alongside competitors like Scoot and AirAsia in offering low-cost access to South Korea, but with the added appeal of direct connectivity to both metropolitan and nature-rich destinations.
Planning Ahead: Flexibility and Affordability
Whether you’re planning a quick city break in Seoul or a relaxed weeklong retreat on Jeju Island, T’way Air’s new routes make it easier and more affordable than ever. Travelers are encouraged to book early and make use of promotional coupons before they expire.
Passengers can also enjoy T’way’s expanding suite of onboard services, which include hot meals, seat selection, and in-flight duty-free shopping—features that blend the comforts of full-service carriers with the affordability of budget airlines.
